Hardy goes to visit Ramanujan in the hospital and mentions the number of his taxi was 14. "I'm afraid that riding in a cab with such a dull number is an ill omen," Hardy says. And Ramanujan replies, "No, not at all; 14 is a very interesting number. It is the only one which can be written as the product of 7 and 2 in two different ways."

Gravity is a force, not an inherit object. No mass=no speed.
However, gravity does place a downwards acceleration on everything on Earth, which is 9.8 metres per second.

>Explain?
The real quote is:
>I remember once going to see him [Ramanujan] when he was lying ill at Putney. I had ridden in taxi-cab No. 1729, and remarked that the number seemed to be rather a dull one, and that I hoped it was not an unfavourable omen. "No," he replied, "it is a very interesting number; it is the smallest number expressible as the sum of two [positive] cubes in two different ways."[1][2]

Anon made a joke by repurposing that exchange between Ramanujan and G.H. Hardy to use the retarded answer the other anon gave of "14" and replace the way the original anecdote reveals Ramanujan's genius in his casual mention without any self-consciousness about it of how he already has random special trivia about a number anyone else (Hardy included) would consider mundane and without special properties by instead stating the stupidly obvious (and therefore funny) observation that 14 is the only product of 7 and 2 and also 2 and 7 because integer multiplication is a commutative operation.
It's similar to when TV show Community had Abed act like Dustin Hoffman in Rain Man except with a comically easy to count answer of 13 bagels recited when they drop compared to the actual Rain Man scene where the character is able to tell there were exactly 246 toothpicks dropped:

For what it's worth, the information transferred in the attractive force between the planets and the Sun appears to travel much faster than the speed of light.

The reason for this is that the orbits are stable: a significantly retarded force would introduce a torque into the system as the planets would be attracted to the position of the Sun minutes to hours previously as they move through the galaxy. The torque would swing the planets unstably.

This is not observed, and under standard cosmology the planets have been in orbit for billions of years. Make your own conclusions.

Gravity travels at most at light speed c. Though usually slower. As opposed to light, its equation of motion is nonlinear, which is usually interpreted to say that it interacts with itself to slow it down.

>> No.11411729

>>11411651
Well it pretty much nixes both general relativity and gravitons/quantum field theory as possible theories of gravitation, or it shows that the planetary orbits are not due to a force of gravity. I think the former is a more reasonable place to start. Either way, you should appreciate that theoretical physicists are quite serious when we say that we don't actually understand gravity: it fails everywhere in some way.

There's a plasma physicist named Hannes Alfvén that conjectured: "Gravitational systems are the ashes of prior electrical systems." I think this idea is worth pursuing. Recently it's occurred to me that gravity is essentially unobserved in particle physics experiments. The assumption is that it's simply too weak to detect at those scales, but on the other hand we are fixated on analyzing collisions and not their aftermath. Just some intuition, but maybe it could be formalized somehow.
